Prepare a reproducible dataset
Use a representative tabular dataset and create a fixed train/test split with stratification where appropriate.
Build an interpretability report. Inspect feature importance.
An interpretability report summarises why a model makes particular predictions and which inputs drive its behaviour. Key considerations include explanation stability, correlation between features, calibration, and how stakeholders will review and act on the report.

An interpretability report summarises why a model makes particular predictions and which inputs drive its behaviour. Key considerations include explanation stability, correlation between features, calibration, and how stakeholders will review and act on the report.
A proposed use case is a model-owner dashboard that surfaces top global and local feature importances along with stability and calibration checks so a human reviewer can validate or challenge model behaviour before deployment.
Use a representative tabular dataset and create a fixed train/test split with stratification where appropriate.
Fit a stable model such as a random forest or gradient-boosted tree and record hyperparameters and random seeds for reproducibility.
Generate global feature importances and local explanations (per-sample) and check explanation stability under resampling.
Produce a document or dashboard that shows metrics, explanation plots, failure cases and actions for human reviewers.
The supplied starter generates a synthetic classification dataset, trains a RandomForestClassifier, computes permutation importances on the test set, prints the test accuracy and a sorted importance table. It does not use real model logs or domain data, and it omits local explanations, stability checks beyond a single permutation run, and any report formatting or dashboards.
X_train, X_test, y_train, y_test = train_test_split(X, y, test_size=0.25, random_state=42, stratify=y)
model = RandomForestClassifier(n_estimators=250, random_state=42)
model.fit(X_train, y_train)
importance = permutation_importance(model, X_test, y_test, n_repeats=10, random_state=42)
report = pd.DataFrame({"feature": columns, "importance": importance.importances_mean})
report = report.sort_values("importance", ascending=False)The code uses a synthetic dataset from sklearn.make_classification rather than real tabular model data, so the feature importances do not reflect a real production model. Explanations are limited to sklearn's permutation_importance on a single test split; there are no local (per-instance) explanations, no SHAP or LIME analyses, no stability or calibration checks, and no formatted report or visualisations.
A proposed extension is to replace the synthetic data with real model inputs and outputs, add SHAP and LIME for local explanations, compute explanation stability under bootstrap resampling, and export a reviewable HTML or Plotly dashboard that documents findings and recommended actions.
This is a potential application pathway, not a delivered product. The supplied starter does not implement this service or validate it with real users.
